How long does kimchi last in the fridge?

I'm curious to know, how long does kimchi typically last in the fridge before it starts to lose its flavor or goes bad? Is there a general rule of thumb that can be applied, or does it depend on the specific ingredients and preparation method used? As someone who enjoys the tangy and spicy taste of kimchi, I'd hate to waste any by not knowing its proper storage duration. Can you shed some light on this topic?
